Bilibili Auto Quality (Ordered)

In the PC web player, automatically set clarity according to the preset order after loading is complete. The entire script is generated by codex + Kimi K2.5.

Usage

  1. In Tampermonkey, create a new script → paste all of setBiliQuality.js → Save (Ctrl+S).
  2. Open any Bilibili video page, and the script will automatically try to set clarity in this order:
    • 4K (120) → 1080P60 (116) → 1080P (80) → 720P (64) → 480P (32) → 360P (16)
    • The first clarity in the video's available list will be selected.
  3. To change the order or only select specific clarity, edit RESOLUTION_ORDER at the top of the script.

Principle

  • Read the clarity list from the page's initial data: window.__playinfo__.data.accept_quality.
  • Call the internal player method to switch clarity. The new player usually has requestQuality(q, audioQuality), while the old player may have setQuality / setPlaybackQuality. The script prioritizes using requestQuality, and automatically tries old interfaces if it fails.
  • If the player is not yet mounted, the script will retry at 500ms intervals within 20 seconds until it succeeds or times out.

Configuration Instructions

  • RESOLUTION_ORDER: Array of clarity codes (from high to low). Example: [80, 64] means first choice is 1080P, if unavailable then 720P.
  • Clarity code correspondence (common):
    • 120 = Ultra-clear 4K
    • 116 = HD 1080P60
    • 80 = HD 1080P
    • 64 = HD 720P
    • 32 = Clear 480P
    • 16 = Smooth 360P

Quick Verification

Open any video page and run in the Console:

const info = window.__playinfo__;
if (info?.data) {
  console.log('Supported clarity codes:', info.data.accept_quality);
  console.log('Clarity descriptions:', info.data.accept_description);
}
const player = window.player;
if (player) {
  const supported = player.getSupportedQualityList?.() ?? [];
  console.log('Player supports:', supported);
}

If player is not defined, wait a moment and try again, or check for "[BiliAutoQuality] Waiting for player to mount..." logs.

Manual Example (Console)

(async () => {
  const q = 64; // 720P
  await window.player?.requestQuality(q, null);
  console.log('Attempted to switch to', q);
})();

Compatibility

Compatible with the new Bilibili PC player (site-wide). If the player is significantly redesigned later, it may need to sync updates to the method name or mounting point.
